Answer 2

Answer:

26.3

Step-by-step explanation:

$3.8 + 1.8 \div (0.2 \times 0.4) \\ = 3.8 + 1.8 \div0.08 \\ = \frac{38}{10} + \frac{18}{10} \div \frac{8}{100} \\ = \frac{38}{10} + \frac{18}{10} \times \frac{100}{8} \\ = \frac{38}{10} +18 \times \frac{10}{8} \\ = \frac{38}{10} + 18 \times \frac{5}{4} \\ = \frac{38}{10} + 9 \times \frac{5}{2} \\ = \frac{38}{10} + \frac{45}{2} \\ = \frac{38 + 225}{10} \\ = \frac{263}{10} \\ = 26.3$
